A frictionless, electrically insulating ramp makes an angle of 0 = 37° above the horizontal. A small charged ball with mass m = 120g and charge q = -28 μC is fixed in place at the bottom of the ramp. An identical ball with the same mass and charge rests at equilibrium on the ramp, some height h above the ground. What is h? For the limit check, investi- gate what happens to h if the ramp becomes extremely steep (i.e., 90°).
